Question

Х+150=800-440 560+b=980-140

Answer 1

1) x+150=800-440
x + 150 = 360
x = 360 - 150 (находим слагаемое, вычитая из суммы известное слагаемое)
x= 210
Ответ: 210

2) 560+b=980-140
560+b = 840
b = 840-570 (находим слагаемое, вычитая из суммы известное слагаемое
b = 280
Ответ: 280

Answer 2

Х+150=800-440
х+150=360
х=360-150
х=210
Ответ: х=210.

560+b=980-140
560+b=840
b=840-560
b=280
Ответ: b=280.

Answer 3

To solve the equations, we need to find the values of the variables 'Х' and 'b'. Let's take it step by step:

1. Equation 1: Х + 150 = 800 - 440

To find the value of 'Х', we first simplify the right-hand side of the equation:

800 - 440 = 360

Now, the equation becomes:

Х + 150 = 360

To solve for 'Х', we subtract 150 from both sides of the equation to isolate 'Х':

Х = 360 - 150 Х = 210

So, the value of 'Х' is 210.

2. Equation 2: 560 + b = 980 - 140

First, simplify the right-hand side:

980 - 140 = 840

Now, the equation becomes:

560 + b = 840

To find the value of 'b', we subtract 560 from both sides of the equation:

b = 840 - 560 b = 280

So, the value of 'b' is 280.

Final solutions: Х = 210 b = 280
